I reverse engineered the bitcoin network mining over the last couple of years and looked at the sustainibility of it from an economic point of view. My research was just published in a peer-reviewed journal.  In short we estimate that between 2012 and 2016: - Two billion dollar of bitcoin was mined ($2,007,950,000, based on daily price) - The miners ran a communal deficit of approximately $558 mln at an energy cost of $0.12 per kWh. An energy price of $0.03 per kWh is required to run a small profit. - Approximately $2.1 bln was invested in hardware. (of which $330 mln was still operational at the end of the measurement period) - Bitcoin hash rate increased by a factor 347,000 - Electricity costs increased rapidly and amounted to almost 900 million dollars. - The estimates of energy consumption of the network are in line with De Vries (2018) and Bitcoin Energy Consumption Index(BECI). - Payback time for hardware was usually between 100 to 300 days, but could be as short as three days. However, his time was often too short to earn the investment back before the mining ceased to be profitable due to increased network hash rate You can read more about it here: https://medium.com/@jonaderks/where-is-the-money-in-bitcoin-mining-64e13d2c94c0Tell me what you think! I can imagine some findings don't match with your personal experiences. |

In 2011, bitcoin dropped from $32 to a mere $2. After this crash it took some time to recover, but the coin got there slowly and surely, rising from the bottom price crash after crash. I believe we experience a similar crash as the 2011 crash now (taken from forbes article) : June 8-12, 2011Peak price: $32 Price decline: 68 percent This was the peak of the great Bitcoin bubble of 2011. Prices rebounded somewhat after this initial plunge, but there followed a long bear market that bottomed out at $2 in November 2011, a total decline of 94 percent. January 17, 2012Peak price: $7.20 Price decline: 36 percent briefly falling to $4.60 before settling around $6.25 August 17-19, 2012Peak price: $15.25 Price decline: 51 percent reaching a low of about $7.50 March 6 and 11, 2013Peak price: $49 Price decline: 33 percent briefly falling to $34 before rising again to $45 April 10, 2013Peak price: $266 Price decline: 61 percent $140 As you can see, after the drastic crash, the coin kept reaching peaks and crashing. The general value kept rising, though. From the $1200 peak, we have fallen back to $180 now (at time of writing) This means, the price has already decreased by 85%. My prediction is that the bottom will be reached in the upcoming days, reaching an ultimate low of just below a $100. After this a slow, but steady rise will start. What do you guys think? |

PULSE BLOCK CREATIONAs the CryptoCoin Revival Foundation, we support coins and innovate them. Our newest innovation is a new way of block generation we implemented in our focus coin Quarkbar, called PULSE. (Quarkbar main topic: https://bitcointalk.org/index.php?topic=587457.0) It slows down block creation to once every five minutes,
except when transaction are sent. When a certain amount of
coins is sent, a block will be created to send the transaction
immediately.It works like this:  We believe PULSE is the best answer to the slow block creation of coins like Bitcoin and an answer to the huge influx of new coins like Dogecoin. Benefits:+ Quick transaction speed when necessary. + Lower inflation: New coins get created at slower speed, when the network is not busy. + Durable: Life of the coin is extended a lot + Efficient: Required network hashses are low. What do you think?Quarkbar main topic: https://bitcointalk.org/index.php?topic=587457.0PULSE FAQWhat is Pulse?Pulse is a revolutionary way of block creation that adjusts the speed of new blocks to the amount of transactions. When there are no transactions or less than 10QB a block is created every 300 seconds. When more than 10QB is sent, a special TX block is created within 30 seconds. This makes it possible to use most newly created blocks to keep the chain synched and sent transactions superfast! How does the difficulty work?Pulse generally spoken adds another layer of difficulty adjustment besides the well known difficulty-index of the merkle-root. How much network power does it need?Pulse ultimately needs 10kh at it's lowest point (where we are now). We will soon launch a difficulty patch that will give it an upthrust and fix the difficulty at about 10.x or 11.x (something close to what it used to be). What about the difficulty adjustmentIf the network regresses and less power is at disposal, the difficulty will be automatically lowered again. The difficulty will lower faster than it will rise. That's why there'.s more pressure downwards. This is to avoid having hard blocks and small miners that can't take it. What about the Rejects?These are a natural part of mining Quarkbar. The projection is that it will be 25% of what is being actively used, so 75% rejects due to Pulse. This means that the difficulty is lower than it should to fix the spacing. |

 QUARKBAR DYNAMIC BLOCK CREATION PULSE is a block creation feature, where blocks are created instantly when a certain amount of transactions is sent. Instead of creating blocks at a fast steady rate, PULSE creates blocks every ten minutes, except when transactions have to be sent. This ensures that newly created coins are rewarded for blocks that were necessary. When the amount of transactions is low, the amount of created blocks is low. This will ensure that new and mature coins can manage their inflation and deflation and secure the future of the coin. The total amount of created coins will stay the same, but the speed of created coins will increase with the usage of the coin. When a coin has a slow start, the market will not be flooded with coins already. No transactions --> Slow creation of new blocks Busy network --> Fast creation of new blocks Mining power needed far lower --> As little as ten nodes are sufficient! PULSE will be implemented into Quarkbar during July and will ensure that Quarkbar is less vulnerable to inflation and transactions are stimulated. Read the white paper hereCODE WILL BE RELEASED ON JULY 6!Update: We're launching the QB-Testnet tomorrow including explorer and will expose the code & documentation to the general public by end of the week. We've coded Pulse to be general purpose so any coin can adopt to it just by adding a simple 'if' condition to their acceptBlock procedure. Update 2: Calculations show that lifetime will likely be extended by ten times the current amount! https://bitcointalk.org/index.php?topic=671622.msg7615862#msg7615862 |

Malicious Quarkbar altcoins tracked down and eliminatedScam prevented and scammer assets frozen
On May 20, The Cryptocoin Revival Foundation (CRF) detected a large amount of scam coins in the blockchain of Quarkbar created by the original developer. Luckily, these coins were held in a small amount of wallets and only 2.3% reached exchanges. Within two days of discovery, CRF created a fork that disabled the malicious wallets. This forgery of coins is comparable to the recent scam at Asiacoin and Beecoin, but the Cryptocoin Revival Foundation was able to disable 97,7% of the fake coins. The exchange account of the scammer has been frozen, resulting in a loss of 0.4BTC for the perpetrator. CRF is proud they were able to disable these coins and hurt the scammer in his wallet.Timeline of eventsMay20: - Block explorer was finished and CRF found out total amount of Quarkbar far higher than expected - CRF found a premine of 15,482,256 Quarkbar in block 1 - CRF was able the transactions and managed to find 97.7% in five separate wallets May 21: - CRF changed the code to cut the wallets off from the blockchain from block 262,500 - The addresses were shared with Quarkbar exchanges and could be linked to one account with 7,000 QB and about 0.4 BTC in other coins. The account could not be traced to a person May 23: - Block 262,500 got passed so wallets are successfully cut off. Revival of QuarkbarOn April 18, The Cryptocoin Revival Foundation (CRF) decided to take over the responsibility of Quarkbar. As it happens quite often, the developer was missing so CRF decided to take control and help the community out. CRF patched up the source, released new wallets and took over communications. Some security issues got fixed and the coin started to flourish again. Scam detectedIt took the team at CRF a while to create a block explorer, but on May 20 they finally managed to do so. The total coin amount seemed to be 15.5 million coins higher than expected so they started an investigation. It turned out the original developer scammed the mining and investing community of Quarkbar. A separate batch of coins was created in block 1, equal to the total amount of coins to be mined, with the purpose to sell them off in an elaborate scam. CRF acted quickly to nip it in the bud. Luckily, the scam did not do much harm, since the coin amount was simply way too high to sell (100% of intended amount of coins). The scammer moved around the coins a lot in an attempt to hide the coins and took his explorer offline. We managed to track down about 97,7% of the coins to five wallets and decided to change the code to simply block those wallets. Taste of his own medicineThe scammer did manage to send about 300,000 Quarkbar to an exchange. In cooperation with this exchange we managed to track the scammer down and freeze his account. This contains coins with a combined value of about 0.4 BTC. The Cryptocoin Revival Foundation team also decided to give the perpetrator a taste of his own medicine by adding a message to his new wallet. We put a scam into his scam to scam him out of his fake coins!  SCAM FREE! In this graph you can follow the money trail and see which wallets we could block. This can also be seen when you use our abe explorer and follow the transactions that start with the creation of the scam coins in block 1. In the abe explorer we have subtracted the blocked wallets from the total amount of coins to give a clear representation of the coins in circulation. The Cryptocoin Revival Foundation is happy about stopping this scammer and froze his assets making his coins useless. Quarkbar is now stronger than ever and officially SCAMFREE! Information about source code changeWe made and addition to the file base58.h in which we added the code to exclude the malicious addresses. These addresses are described from line 393 as LUCKY_WINNERS. His price? A wallet full of useless Quarkbar! Code fragment: static const CBitcoinAddress LUCKY_WINNERS[5] = {
CBitcoinAddress("QUwKPLAGxAYQtkTeD5opwD2Q4fvLWwXesb"), //14M
CBitcoinAddress("QN4cdcaVJtbk6SuLQbDY1u4G2ZGyxEfbcg"), //800k
CBitcoinAddress("QWjTNd1d47zNi6VdkTGx4ZQYtBodJfHiiQ"), //50k
CBitcoinAddress("QeDoawWtLN32hJC6jpHs1k3RDiDU3kv2Zw"), //11.8k
CBitcoinAddress("QaRKRXjiRWVDjQCNNWtQYCMrkSH4sJxfCH") //999
};Quarkbar is a super secure quark-based altcoin (CPU/GPU mining) that is fast, very rare and with no premine, very fair! It was taken over by the community! More information can be found on www.quarkbar.net. About Cryptocoin Revival FoundationThe Cryptocoin Revival Foundation is an initiative that started on Bitcointalk. A group of users was dissatisfied about altcoin developers disappearing and decided to work together to provide stability and technical help to altcoins that show great promise, but have been deserted by their developers. This way, the mining was not wasted, people will not have worthless coins and altcoins in general will become more reliable. The foundation has no profit motivation and relies on donations from members. Contact cryptocoinrevival@gmail.com - www.cryptocoinrevival.com - https://bitcointalk.org/index.php?topic=576714.0END ###

To get an indication of the amount of QB around, the first step is to see how many coins people have in their personal wallets. You would really help out if you could post about how much coins you have combined in your wallets. It would help if you PM me your total amount so I know which amounts are real. NOTE: This is only an indication and can easily be messed up by jokers. |
